TSMC Reveals 2nm Node: 30% More Performance by 2025

> Title: “30% More Performance”

The article title appears incorrect.

Looking at the table in the article, it’s only be 10-15% more performant (not “30%”) for the same power used.

The “30%” is how much more energy efficient it would be at the old performance (23%-30%).

I don’t understand these things well but in a way, doesn’t that mean I can get 30% more CPUs running for my power usage?

I guess in a lot of cases that doesn’t exactly help.

No.

The table says, if you maintain the same power usage you’d get a 10-15% more performance. If you maintain the same performance, you save 23-30% power previously used.

But also kind of yes. If you've got a fixed power budget, and you replace your old cpus with new ones, running at the same performance, now you're using 23-30% less power use (ignoring non-cpu power budget), and you can bring that many more cpus online at the old performance target.

For multicore CPUs or GPUs, 30% lower power means, you get 30% more performance at the same power.

I wonder of Intel wins back Apple's business in the near future.

Apple’s current situation where it designs CPUs and uses TSMC to fabricate them is very advantageous for them. If Apple uses Intel in the future it would very likely be to fabricate Apple designed CPUs rather than source CPUs from Intel.

Totally agree, but I think that would be fascinating to see. It's essentially the end-goal of a lot of the political/national security growing concern over semiconductor capacity. I could imagine it being pretty subsidized and even a token inclusion at first just due to outside pressures and incentives, but I'm just speculating.

Maybe some, but Intel would need to take steps to prove that they're trustworthy. In the event that Intel's fabs become the best in the future, there's a situation that will happen where Intel might be tempted to use it all up on their own products because that is the most profitable for them.

Can anyone, except maybe intel, compete with TSMC?

If we accept Intel as a valid competitor, then samsung would be.

No, as of today.

Any other pure-play? I don't think so. Even Intel want to rely on TSMC [0]

Adding to this — can anyone compete with ASML? (Follow-up: how reliant on ASML is TSMC? My understanding is "very reliant.")

Most semiconductor equipment manufactoring companies don't really compete with anyone. This includes ASML, Applied Materials, Lam Research, and KLAC. They might overlap a bit but their main business are usually monopolies due to how advance and specific the technology is. You aren't going to find many companies wanting to join in because they are just going to be WAY far behind the leaders and in this field only the best get their equipment bought because of how expensive mistakes can be.

Isn't Samsung a more likely competitor to TSMC than Intel at this point?

Both of them offer foundries to outside companies. Samsung even made chips for Apple. Samsung is suppose to hit 3nm this year, and they plan to beat TSMC by 2030 as the world largest foundry.

Next gen handheld gaming will be insane

No wonder they want to destroy TSMC before china takes it back

How do you go from "next gen handheld gaming will be insane" to "no wonder they want to destroy TSMC before china takes it back?"

Idk, I don’t think the West can coexist with high end handheld gaming devices.

What do you mean "takes it back"? It never belonged to China to begin with.

Its future, because the US wants to destroy it

It would be sad to loose such thing

Way to misrepresent that paper.

The US does not want to destroy TSMC. There was a paper advocating for a scorched earth policy to deter China from invading Taiwan.

They do, they prep supply chain to not depend on them already, and are moving some parts elsewhere, no fire, no explosion needed, can't do 2 Beirut

And it's not just TSMC, they are already, yet again, forcing their supposed "allies" from EU to comply

Perhaps to get replaced with Wallmarts? for more US presence

>It never belonged to China to begin with.

Sure it does, sometimes also called Taiwan.
